Technical Field

[0001] The utility model relates to the technical field of circular saw machine clamps, in particular to a circular saw machine positioning clamp. Background Art

[0002] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing circular saw positioning fixture does not have good versatility, the clamping blocks of the existing fixture are too simple for clamping the cutting piece, and when cutting and processing columnar or special-shaped cutting pieces, the corresponding clamping blocks need to be replaced, the replacement frequency is high, and the practicality is poor, which is in urgent need of improvement. Therefore, we propose a circular saw positioning fixture. Utility Model Content

[0009] Screw blocks are fixedly installed on both sides of the front wall of the threaded barrel, and a screw rod b is screwed on the middle part of the screw block through a screw hole. The inner end of the screw rod b is rotatably connected to the clamping block through a bearing, and the other end of the screw rod b extends to the outside of the clamping block. It can be used in combination with components such as arc grooves, limit blocks and screw rods. If a columnar cutting piece needs to be clamped, the clamping block can be driven inward by a push rod motor, and the cutting piece can be aligned with the arc groove. If a normal cutting piece needs to be clamped, the limit block can be contracted, and the two sets of clamping blocks can be moved inward for clamping. If a special-shaped cutting piece needs to be clamped, the screw rod b can be rotated forward and backward, and the screw rod b can drive the threaded barrel to move through the screw block until the limit block is aligned with the clampable flat surface of the cutting piece. Subsequently, the screw a is rotated to drive the limit block to move inward, so that the limit block can locally position and clamp the special-shaped cutting piece, making the clamp suitable for clamping a variety of cutting pieces, with strong versatility and reduced replacement frequency.

[0010] As an optional scheme of the technical scheme of the present application, the movable rod extends into the sleeve, and a slot is provided at the front end of the movable rod. An insertion rod is movably inserted through the front side of the sleeve, and a stop block is fixedly installed on the outer end of the insertion rod. The stop block is fixedly connected to the sleeve by a tension spring and can be used in conjunction with components such as the sleeve and the insertion rod. If different sizes of clamps are replaced in the later stage, the insertion rod can be moved outward by applying force to separate the insertion rod from the slot, and then the specified model of clamps can be replaced. The insertion rod is released, and the tension of the tension spring can drive the insertion rod to move inward and reset, and then plug it into the slot, so that the clamp block can be detachably assembled, which is convenient for the later replacement of clamps with multiple signals, and the limiting structure is easy to disassemble and assemble.

The frame can be detachably fixed by the support rods and their positioning blocks to ensure the stability of the frame limit to prevent shaking and shifting.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses a positioning clamp for a circular saw, which is provided with an arc groove, a limit block and a screw rod. When the positioning clamp for a circular saw is used, if a columnar cutting piece needs to be clamped, the clamp block can be driven to move inwards by a push rod motor, and the cutting piece can be aligned with the arc groove. If a normal cutting piece needs to be clamped, the limit block can be contracted, and the two groups of clamp blocks can be moved inwards for clamping. If a special-shaped cutting piece needs to be clamped, the screw rod b can be rotated forward and reversely, and the screw rod b can drive the threaded barrel to move through the screw block until the limit block is aligned with the clampable flat surface of the cutting piece. Then, the screw rod a can be rotated to drive the limit block to move inwards, so that the limit block can locally position and clamp the special-shaped cutting piece. The clamp is suitable for clamping a variety of cutting pieces, has strong versatility, and reduces the replacement frequency.

[0016] 2. The utility model provides a positioning fixture for a circular saw machine, which is provided with a sleeve and an insert rod. If a clamp of a different size is replaced later, the insert rod can be moved outward by applying force to separate the insert rod from the slot, and then the clamp of the specified model can be replaced.
